Python vs Cpython
..., and depending on the project you're working on, it may be a good idea to test and profile your Python code on several implementations. Having worked on Java+Jython projects before, you can run into many surprises because devs haven't tested their libs enough on this platform.

Wait for all promises to resolve

That said this wouldn't ever be used on a website. But for load-testing/integration test...maybe.
Example code:

How does grep run so fast?
...lta table entries in such a way that it doesn't need to
do the loop exit test at every unrolled step. The result of this is
that, in the limit, GNU grep averages fewer than 3 x86 instructions
executed for each input byte it actually looks at (and it skips many
bytes entirely).
